Federalist 39: 6
On comparing the Constitution planned by the convention with the standard here fixed, we perceive at once that it is, in the most rigid sense, conformable to it. The House of Representatives, like that of one branch at least of all the State legislatures, is elected immediately by the great body of the people. The Senate, like the present Congress, and the Senate of Maryland, derives its appointment indirectly from the people. The President is indirectly derived from the choice of the people, according to the example in most of the States. Even the judges, with all other officers of the Union, will, as in the several States, be the choice, though a remote choice, of the people themselves, the duration of the appointments is equally conformable to the republican standard, and to the model of State constitutions The House of Representatives is periodically elective, as in all the States; and for the period of two years, as in the State of South Carolina. The Senate is elective, for the period of six years; which is but one year more than the period of the Senate of Maryland, and but two more than that of the Senates of New York and Virginia. The President is to continue in office for the period of four years; as in New York and Delaware, the chief magistrate is elected for three years, and in South Carolina for two years. In the other States the election is annual. In several of the States, however, no constitutional provision is made for the impeachment of the chief magistrate. And in Delaware and Virginia he is not impeachable till out of office. The President of the United States is impeachable at any time during his continuance in office. The tenure by which the judges are to hold their places, is, as it unquestionably ought to be, that of good behavior. The tenure of the ministerial offices generally, will be a subject of legal regulation, conformably to the reason of the case and the example of the State constitutions.
